Leopard seal geolocation and activity data from Bird Island, South Georgia, 2003 to 2013
These are light level and activity data collected from BAS geolocators that were deployed on 4 Leopard Seals hauled out on Bird Island, South Georgia. Tags were deployed between May 2003 and June 2013. One seal Y5282(B4942) was tracked during two non-consecutive years using two different identification flipper tags. There are three data types for each seal a) the unprocessed light sensor data b) the unprocessed activity (wet/dry) data and c) The estimated positions estimated using the BAStag and SGAT packages in R. All files are in the CSV format and each folder has a readme.txt file describing the data structure of the files within. The data are reported in detail in Staniland et al. 2018 'Long Term Movements and Activity Patterns of an Antarctic Marine Apex Predator: The Leopard Seal' PLOSone

Methodology:
Data was downloaded from BAS GLS tags using proprietary BAStrack software 'decompressor'. Clock drift was accounted for using the startup time of each tag.
Loggers measured light levels every 60 seconds recording the maximum light level in a 10 minute period. Salt-water immersion was assessed every 3 s and the number of positive saltwater tests in each 10 min interval recorded: an immersion value of 0 indicates that the logger was completely dry and 200 that it was completely wet. Processed Estelle data was created from the light data using the BAStag and SGAT packages in R. Full details of the processing can be found in the Staniland et al (2018) PLOSone paper.
Data collection:
Data were collected by BAS MK7 and M9 GLS (geolocator) tags.

Data quality:
Data were corrected for any clock drift over time using the 'decompressor' programme and the startup times of each tag.
